Typical PSEG Long Island path:
Total potential: $12,000–$25,000+. Most Long Island homeowners see only the PSEG number. Adding state layers can triple it.
Your out-of-pocket: $5,000–$10,000 after stacking (vs. full $15,000–$22,000 equipment cost for a heat pump).
Energy savings: $1,200–$1,600 per year (Long Island winters are cold; heat pumps pay for themselves in 3–5 years).
